If you are not using the RTEMS build infrastructure then you are likely
not building a library for RTEMS but a relocatable file (-r).
I would highly recommend using the RTEMS build infrastructure to build
RTEMS and then using whatever technique you want to build your
application. Stick to the known good make structure for RTEMS itself
and you will get two libraries -- one for RTEMS itself and one for the
BSP.
You have introduced problems by not using the known good build procedure.
